| * kconfig: refactor .gitignoreMasahiro Yamada2021-04-251-10/+3
| | | | | | | | | | | | | | | | | | | | | | | | Add '/' prefix to clarify that the generated files exist right under scripts/kconfig/, but not in any sub-directory. Replace '*conf-cfg' with '[gmnq]conf-cfg' to make it explicit, and still short enough. Use '[gmnq]conf' to combine gconf, mconf, nconf, and qconf.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mark Kconfig "comment" lines with "*** <commentstring> ***" so that it is clear that these lines are comments and not some kconfig item that cannot be modified.

| * kconfig: nconf: stop endless search loopsMihai Moldovan2021-04-161-1/+1

The reason is that in this case, the starting point will be set to -1 or n, which is then translated into (n - 1) (i.e., the last entry of the page) or 0 (i.e., the first entry of the page) and finally the search begins. This continues to work fine until the index reaches 0 or (n - 1), at which point it will be decremented to -1 or incremented to n, but not checked against the starting point right away. Instead, it's wrapped around to the bottom or top again, after which the starting point check occurs... and naturally fails. My original implementation added another check for -1 before wrapping the running index variable around, but Masahiro Yamada pointed out that the actual issue is that the comparison point (starting point) exceeds bounds (i.e., the [0,n-1] interval) in the first place and that, instead, the starting point should be fixed. This has the welcome side-effect of also fixing the case where the starting point was n while searching down, which also lead to an infinite loop. OTOH, this code is now essentially all his work. Amazingly, nobody seems to have been hit by this for 11 years - or at the very least nobody bothered to debug and fix this.

I do not see any good reason to use the 'float' type just for the division by 2. All the call-sites pass a non-NULL pointer to the first argument, so 'if (win == NULL) win = stdscr;' is dead code. 'if (startx != 0) x = startx;' is dead code because 'x' will be overridden some lines below, by 'x = startx + (int)temp;'. All the call-sites pass a non-zero value to the second argument, so 'if (starty != 0)' is always true. getyx(win, y, x) is also dead-code because both 'y' and 'x' are overridden. All the call-sites pass 0 to the third parameter, so 'startx' can be removed. All the call-sites pass a non-zero value to the fourth parameter, so 'if (width == 0) width = 80;' is dead code. The window will be refreshed later, so there is no need to call refresh() in this function. Change the type of the last parameter from 'chtype' to 'int' to be aligned with the prototype, 'int wattrset(WINDOW *win, int attrs);' I also slightly cleaned up the indentation style.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current attributes setup code is strange; the array attribute[] is set to values outside the range of the attribute_t enum. At least, attributes_t attributes[ATTR_MAX+1] = {0}; ... should be int attribute[ATTR_MAX+1] = {0}; Also, there is no need to hard-code the color-pair numbers in attributes_t. The current code is messy. Rewrite it. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
| * kconfig: nconf: remove unneeded default for menu promptMasahiro Yamada2021-04-141-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | The rootmenu always has a prompt even if the 'mainmenu' statement is missing in the top Kconfig file. conf_parse() calls menu_add_prompt(P_MENU, "Main menu", NULL) in this case.

| * kconfig: nconf: get rid of (void) casts from wattrset() callsMasahiro Yamada2021-04-142-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 10175ba65fde ("nconfig: Silence unused return values from wattrset"). With this patch applied, recent GCC versions can cleanly build nconf without "value computed is not used" warnings. The wattrset() used to be implemented as a macro, like this: #define wattrset(win,at) \ (NCURSES_OK_ADDR(win) \ ? ((win)->_attrs = NCURSES_CAST(attr_t, at), \ OK) \ : ERR) The GCC bugzilla [1] reported a false-positive -Wunused-value warning in a similar test case. It was fixed by GCC 4.4.1. Let's revert that commit, and see if somebody will claim the issue. [1]: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=39889 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

| * kconfig: use /boot/config-* etc. as DEFCONFIG_LIST only for native buildMasahiro Yamada2021-04-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the .config file is missing, 'make config', 'make menuconfig', etc. uses a file listed in DEFCONFIG_LIST, if found, as base configuration. Ususally, /boot/config-$(uname -r) exists, and is used as default. However, when you are cross-compiling the kernel, it does not make sense to use /boot/config-* on the build host. It should default to arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG). UML previously did not use DEFCONFIG_LIST at all, but it should be able to use arch/um/configs/$(KBUILD_DEFCONFIG) as a base config file. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | sym_change_count has no good reason to be 'int' type. sym_set_change_count() compares the old and new values after casting both of them to (bool).

| * kconfig: nconf: fix core dump when searching in empty menuMasahiro Yamada2021-04-141-3/+7

A menu can be empty when all the options in it are hidden by unmet 'depends on'. For example, menu "This menu will be empty" config FOO bool "foo" depends on BROKEN endmenu If you visit this menu and press a '/' key and then another key, nconf crashes with: Floating point exception (core dumped) When the number of items is zero, it does not make sense to search in the menu. In this case, current_item() returns NULL, and item_index() ERR, but get_mext_match() does not check it. Let's make get_mext_match() just return if the menu is empty. While I am here, change items_num from 'int' to 'unsigned int' because it should never become negative. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | allnoconfig_y is an ugly hack that sets a symbol to 'y' by allnoconfig. allnoconfig does not mean a minimal set of CONFIG options because a bunch of prompts are hidden by 'if EMBEDDED' or 'if EXPERT', but I do not like to hack Kconfig this way. Use the pre-existing feature, KCONFIG_ALLCONFIG, to provide a one liner config fragment. CONFIG_EMBEDDED=y is still forced when allnoconfig is invoked as a part of tinyconfig. No change in the .config file produced by 'make tinyconfig'. The output of 'make allnoconfig' will be changed; we will get CONFIG_EMBEDDED=n because allnoconfig literally sets all symbols to n.

| * kconfig: change defconfig_list option to environment variableMasahiro Yamada2021-04-149-29/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "defconfig_list" is a weird option that defines a static symbol that declares the list of base config files in case the .config does not exist yet. This is quite different from other normal symbols; we just abused the "string" type and the "default" properties to list out the input files. They must be fixed values since these are searched for and loaded in the parse stage. It is an ugly hack, and should not exist in the first place. Providing this feature as an environment variable is a saner approach. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current option parse code is clumsy. The 's' option is separately handled in an if-conditional due to the following code: input_mode = (enum input_mode)opt; If 's' is moved to the switch statement, the invalid value 's' would be assigned to the input_mode. Another potential problem is that we are mixing 'enum input_mode' and ASCII characters. They could overwrap if we add more input modes. To separate them out, set the flag field of long options to a pointer of input_mode_opt. For mode select options, getopt_long() returns 0, which never causes overwrap with ASCII characters that represent short options. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

| | | | | | | | You can get the Qt version by running "pkg-config --modversion Qt5Core" or something, but this might be useful to get the runtime Qt version more easily. Go to the menu "Help" -> "About", then you can see it. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

* kconfig: qconf: convert to Qt5 new signal/slot connection syntaxMasahiro Yamada2020-12-081-58/+78
| | | | | | | | | | | | | | | | | Now that the Qt4 support was dropped, we can use the new connection syntax supported by Qt5. It provides compile-time checking of the validity of the connection. Previously, the connection between signals and slots were checked only run-time. Commit d85de3399f97 ("kconfig: qconf: fix signal connection to invalid slots") fixed wrong slots. This change makes it possible to catch such mistakes easily. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Tested-by: Boris Kolpackov <boris@codesynthesis.com>
